OPHTHALMIC MOUNTING.

Application filed-ito iember so, 1923. Serial No. 677.8 14.

The present invention relates 'to an improved formof ophthalmic mounti'ng and has particular reference to the so-c'alled all celluloid frame. r

An im ortant object of the present inven tion is to provide amounting of this nature wherein a saddle form of bridge'i's used in such a manner that the said bridge may be adjusted as desired. I j

I-Ie'r'etofore the sO-called all celluloid frames have been so constructed that it has been impossible to adjust the bridge to the patients face as has been desirable, and this invention has, therefore, for an important object thereof, to do away with the inconvenience of this form of mounting by providing a form of bridge that will not in any way detract from the beauty of this type of mounting, but at the same time will be subject to adjustment.

Another very important object of the invention is to provide a mounting of this nature that will be strong, durable, very simple and inexpensive in construction and that is well adapted for the uses for which it is desired.

Other objects and advantages of the invention will become apparent during the course of the following description.

In the drawings, wherein like numerals are employed to designate like parts throughout the same,

Figure 1 is a rear elevation of my improved form of ophthalmic mounting,

Figure 2 is a fragmentary sectional view thereof illustrating one form of, bridge anchoring means,

Figure 3 is a ing, and

Figure 4 shows a slightly modified form of bridge anchoring means.

In the drawings, wherein for the purposes of illustration is shown the preferred embodiment of my invention, the numeral 5 designates a mounting which comprises the eyes 6, improved bridge 7 and end pieces 8.

My improved form of bridge comprises a metallic inner member 9, which is shaped as is desired and has the curved portions to facilitate the adjustment, while the ends thereof terminate in the barb 11. The metallic inner core 9 of the bridge is covered with a cellulose composition such as zylonite 12. The cellulose composition 12 may be top plan view of the mountsuitable recess which appliedeither by spraying, dipping or the l ke, in 'a, liquid composition, or the core 9 may be insei ted through a length of tube stock before it has. been bent. After the core 9 has been placed within a length of tube stock both the cellulose composition and metallic bridge may be formed to the desired configuration, but. I desirethat the adjusting portions 10 be providedto facilitate the adaptation ofthe bridge to numerous typesoffaces. The eyes 6 are preferably heated to a semi-plastic condition, after which the barbed ends 11, which is to be understood are not covered with the cellulose composition 12, are driven within the same in such a .manner that they will become firmly embedded in the eyes, and after the eye portions 6 have been allowed to cool again and set up, the bridge 7 will. besecurely anchored in position. It will, of course, be understood that the barbed ends 11 will prevent any displacement of the bridge 7 with respect'to the eye pieces The cellulose'composition 12 may then be cemented to the eye portions 6 as at 13, thus forming an unrecognizable joint between the two so that a mounting will be provided that will in every way resemble the heretofore so-called all celluloid mounting with the additional desirable feature that the bridge 7 may be adjusted.

In Figure 4 a slight modification of the anchoring means is shown, wherein a form J of plate 1% is carried by the outer extremities of the inner core 9 of the bridge 7. The plate 1 1 is adapted to be received within a is communicated with the lens seat 16, said plate 14 being so disposed that it will not in any way interfere with the reception of the lens 16'when the mounting is in use. The plate 14 may be held in place by suitable cement so as to form a rigid anchor for the bridge, and

if it is desired, small apertures 17 may be so provided in the plate it that additional means will be had to form a good anchor.

In accordance with the above invention, it, will be seen that I have devised means wherein an adjustable formof an all celluloid I mounting may be had whereby the bridge may be so ad usted that it will accommodate itself to various shaped and SlZQCl faces, thus makingit much easier to fit such a form of mounting to a. patient while at the same time shape, size and arrangement of parts may be resorted to Without departing from the spirit of the invention or the scope of the sub-joined claims.

Having thus described my invention, I claim:

1.. An ophthalmic mounting of the char-- acter described comprising eye pieces formed from cellulose composition material having recesses formed therein, an adjustable bridge interposed therebetWeen plates carried by the adjustable bridge, said plates being adapted to be received Within the recesses formedwithin the eye pieces and a cellulose composition covering arranged on the adjustable bridge.

2. In a device of the character described,-

a pair of non-metallic lens rims having a lens groove therein and an internal recess communicating With the lens groove, a me-' lens groove therein and an internal recess communicating With the lens groove, a metallic bridge having terminal plates extending into the recesses and cementious means for securing the plates in the recesses.

4. In a device of the character described, a pair of non-metalliclens rims having a lens groove and an internal recess co1nmuni eating With the lens groove, a metallic bridge having recessed terminal plates extending into the recesses, anda cement securing the plates in the recesses, said cement extending into the recesses in the plates.
